The regulating of a structure and a pores volume of activated carbons by mechanical, chemical and thermal activations of agricultural wastes, such as apricot kernel shells were studied. The mechanical activation was provided in the grinding mill, in the aqueous medium. The chemical activation was implemented by treatment with sulfuric, hydrochloric, phosphoric acids at the concentrations of 5%–40% and by zinc chloride at the penetration coefficients of 0.1÷0.6. The thermal activation was effected in carbon dioxide atmosphere at the temperatures of 300÷100    ? ?. It was researched an influence of acid concentration, ZnCl 2  coefficient of impregnating, CO 2  temperature per volume of micro-, meso- and macropores. Activated carbons have arranged porous structures in the following line: processed by ZnCl 2  and CO 2  u003e processed by ZnCl 2  u003e processed by H 2 SO 4  u003e processed by H 3 PO 4 . For the samples are treated by ZnCl 2  and   subsequent CO 2 , the activation optimal parameters are following: temperature of CO 2  =500  ? ?; the penetration coefficient = 0.4.
